3. Sir Elton John & More!

Gwen Stefani (in Zuhair Murad) cuddled up with the men of the evening, David Furnish and Sir Elton John at their 20th annual post-Oscars bash. Although the couple weighed in on each other's outfits, they went their own way fashion-wise. "He went and got his own Tom Ford," said Sir Elton of his husband's look. "This is by Alex Couture of Beverly Hills. And it's got my name on the back. I want to be a little glitzy because we've got Adam Lambert coming. We've got Katy Perry. So I wanted to try and wear something a little sparkly."

13. Miley Cyrus and Liam Hemsworth

Miley Cyrus and boyfriend Liam Hemsworth painted the town in retro chic. "I just always love pinup girls," Cyrus said of the inspiration behind her Roberto Cavalli gown. "I think it's the most fabulous time."
